Connector ldentification and Wire Harness Routing
JHow to ldenti{v Connectors:
ldentification numbers have been assigned to all connectors. The number is preceded by the letter "C" for connectors,"G" for single ground terminals ot "f" lor single non-ground terminals.

Fuel Gauge
Gauge Test
NOTE: Refer to page 23-123 for the fuel gauge system
circuit.
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testing.
2. Remove the rear seat (see section 20).
Remove the protective cover and access panel from
the tloor.
With the ignition switch OFF, disconnect the 3p con-nector from the fuel gauge sending unit.

PROTECTIVECOVER
Connect the voltmeter positive probe to the
YEL/WHT terminal and the negative probe to the
BLK/WHT terminal, then turn the ignition switch ON(ll). The.e should be between 5 and 8 V.
a lf the voltage is as specified, go to step 6.a lI the voltage is not as specified, check for- an open in the YEL/WHT, BLU/WHT or
BLK/WHT wire.- poor ground (G501, G502).
3P CONNECTOR
View from wire side
6.Turn the ignition switch OFF. Attach a jumper wire
between the BLKMHT and YEL/WHT terminals,
then turn the ignition switch ON {1.,.
Check that the pointer of the fuel gauge starls mov-
ing toward the "F" mark.
CAUTION: Turn the ignition switch OFF before the
pointer reaches "F" on the gauge dial, Failure to do
so may damage the tuel gauge.
NOTE: The fuel gauge is a bobbin (cross-coil) type
gauge, hence the fuel level is continuously indicat-
ed even when the ignition switch is OFF, and thepointer moves more slowlv than that ol a bimetal
rype gauge.
a lf the pointer ol the fuel gauge does not move at
all, replace the gauge.
a It the gauge is OK, inspect the fuel gauge send-
ing unit.

)
Function Test
NOTE: To test, remove the driver's door panel (see sec-
tion 20), then disconnect all of the connectors from the
ooor panet.
Mifior Test
NOTE: Check the No. 17 {7.5 A) fuse in the under-dashfuse/relay box before testing.
One or both inoperative:
Check for voltage between the BLK//EL terminal and
body ground with the ignition switch ON {ll).There should be battery voltage.
. lf there is no voltage, check for:* Blown No. 17 (7.5 A) fuse in the under-dash
fuse/relay box- An open in the BLK/YEL wire
. lf there is battery voltage, go to step 2.
Check for continuity between the BLK terminal and
body ground.
There should be continuity; check for.* An open in the BLK wire- Poor ground (G501 (sedan), G502)
vrllBtxt YEL/RED' aa*\
Left miror inoperative:
Connect the BLK,^/EL terminal of the 1OP connector to
the YEVRED1terminal and the YEL /VHT (or YEL/BLK1)
terminal to body ground with iumper wires.
The left mirror should tilt down (or swing left) when you
turn the ignition switch ON (ll).
a lf the mirror does not tilt down (or does not swing lett).check for an open in the YEL/WHT {or YEL/BLKr}wire between the left mirror and the switch. lf the wireis OK, check the lett mirror actuaror.
a lf the mirror neither tilts down nor swings left, repair
the YEL/REDr wire between the letr mirror and theswtlcn.
a lf the mirror operates properly, check the mirror
swttcn.
Right mirrol inoperative:
Connect the BLK/YEL terminal of the 10P connector to
the BLU,^/VHT terminal and the YELMHT {or BLU/BLK)
terminal to body ground with jumper wires.
The right mirror should tilt down (or swing left) whenyou turn the ignition switch ON (ll).
a lf the mirror does not tilt down (or does not swing left),
remove the right door panel and check for an open in
the YEL/WHT (or BLU/BLK) wire between the right mir-
ror and the switch. lf the wire is OK, check the right
mirror actuator.
a lf the mirror neither tilts down nor swings lett, repair
the BLU/WHT wire between the right mirror and the
swrtch.
a lf the mirror operates properly, check the mirror
switch.

1.Remove the driver's door panel, and disconnect the
10P connectorfrom the master switcn.
Inspect the connector and socket terminals to be
sure they are all making good contact.
a lI the terminals are bent, loose or corroded, reDair
them as necessary, and recheck the system.
a lf the terminals look OK, make the following in-
put tests at the connector terminals.- It a test indicates a problem, find and correct
the cause, then recheck the system.- lf all the input tests prove OK, the power win-
dow master switch must be taulty; reDlace it.
